Gastrointestinal parasitic infections: Prevalence and risk factors in West Ismailia, Arab Republic of Egypt.

BACKGROUND: This study aimed to determine the prevalence of gastrointestinal parasites (GIP) in the rural community of West Ismailia and its associated risk factors. Human infection by GIP is natural and expected. There are few records concerning parasitic infection in the rural areas of the Ismailia Governorate. METHODS: From 520 individuals, sociodemographic and risk factors information were retrieved. Fecal samples were collected, concentrated, and tested for GIP infection using a microscopic examination. RESULTS: The West Ismailia study population had a 40.4% prevalence of GIP infection, including single and concomitant parasite infections. The most common cause of GIP infection was protists (38%). Entamoeba sp., Blastocystis sp., and G. duodenalis were the most common parasites. Poly-parasitism was prevalent within the West Ismailia region. Age, abdominal symptoms, perianal itching, ownership of numerous animal species, exposure to turbid water, previous parasitic infection (PPI), and non-treatment reception of PPI were all considered significant factors associated with GIP infection. Specific individuals from the same family have been observed to have identical GIP. CONCLUSION: GIP infection remains underestimated in rural areas. Periodic screening and treatment for GIP infection in children and public education on GIP hazards and prevention, focusing on personal hygiene, are recommended. Family members of affected individuals should be screened and treated for GIP.

Subtypes and phylogenetic analysis of Blastocystis sp. isolates from West Ismailia, Egypt.

In Egypt, Blastocystis sp. is not yet on the diagnostic list of parasitology reports, and information about its subtypes (STs) is scarce. This study investigated its prevalence and its STs/alleles, performed phylogenetic analysis, and considered the distribution of risk factors associated with Blastocystis sp. infections in West Ismailia, Ismailia governorate. Sociodemographic data, exposure factors, and previous parasitic infection status were recorded for symptomatic and asymptomatic individuals. Microscopy, polymerase chain reaction, sequencing, and phylogenetic analysis for Blastocystis sp. isolated from fecal samples were performed. Eighty Blastocystis sp.-infected individuals (15.3%) were examined. The age of the individuals ranged between 0.60 and 85.0 (mean 17.10 ± 15.70), the male/female ratio was 33/47, and the asymptomatic/symptomatic ratio was 55/25. The findings demonstrate clear evidence of direct contact with animals, poor water quality, and previous parasitic infections. Eleven samples yielded three Blastocystis STs (ST1: allele 4, ST2: alleles 9 and 12, and ST3: allele 34), with ST3 (45.5%) representing the most common subtype. Phylogenetic analysis with a robust bootstrap revealed three distinct clades for isolates of each subtype. This study updates the epidemiological knowledge of the distribution of Blastocystis sp. STs in Egypt and expands the current understanding of the prevalence, risk factor frequencies, and genetic diversity of this protist in the studied area.

Gastrointestinal parasites diagnoses at the primary health care units: a comparative analysis of diagnostic abilities of parasitology staff technicians versus medical parasitologists in Ismailia, Egypt.

BACKGROUND: This study aims to compare parasitology technicians (ParaTechs) with medical staff parasitologists (MedParas) in terms of diagnostic ability and to assess the actual occurrence of gastrointestinal parasites in selected faecal samples from primary health care units (PHCUs). METHODS: The study included five PHCU ParaTechs in the El-Kassassin rural area, evaluated using a scoring system for their knowledge, skills, practices and parasitology laboratory facilities. Seventy-five faecal samples previously examined for ova and parasites by ParaTechs were chosen for re-evaluation by MedParas. RESULTS: The most deficient ParaTechs-related factor was the parasitological knowledge, which scored 23.9% of the maximum score, while ParaTechs had acceptable levels of skills and practices, scored 60% and 61%, respectively. Compared with MedParas, false positive ParaTech diagnoses made up 8.8% of all negative samples, while false negative diagnoses made up 85.4% of all positive samples. ParaTechs underestimated the count or misidentified the type of parasites in one-third of the true positive samples. The overall rate of misdiagnosis among ParaTechs was 53.3% of all samples. CONCLUSIONS: Regular ParaTech training, including culture and staining at parasitology labs, and collaboration between the Ministry of Health and Population and academic institutions are essential to increase ParaTechs diagnostic abilities.

Psychrometric Properties of the Arabic Version of the Problem Areas in Diabetes Scale in Primary Care.

Background: The Problem Areas in Diabetes (PAID) scale is a reliable and valid tool that is widely used for diabetes-distress screening, but the Arabic version of the scale lacks validity and reliability analysis in primary healthcare (PHC) patients. Our study aimed to evaluate the psychometric properties of the Arabic version of the PAID (AR-PAID) scale among Egyptian patients with type 2 diabetes mellitus (T2DM) in PHC settings. Methods: We conducted a cross-sectional study on a convenience sample of 200 patients from six rural PHC settings in the Ismailia governorate. The confirmatory factor analysis (CFA) was performed to test the goodness-of-fit to the predefined models of the PAID. Convergent construct was evaluated through correlations with the Arabic versions of the Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and 5-item World Health Organization Well-Being Index (WHO-5), additionally glycated hemoglobin (HbA1c) levels. Discriminant validity was evaluated through associations with patients' sociodemographic and clinical characteristics. Reliability was evaluated through internal consistency (Cronbach's α) and test-retest reliability analysis (intraclass correlation coefficient, ICC). Results: The CFA demonstrated the best fit for a four-factor model. The AR-PAID was significantly correlated with the following measures: PHQ-9 (rho = 0.71, p < 0.001), GAD-7 (rho = 0.50, p < 0.001), WHO-5 (rho = -0.69, p < 0.001), and HbA1c (rho = 0.36, p < 0.001), supporting sound convergent validity. Discriminant validity was satisfactory demonstrated. Internal consistency was excellent (α = 0.96) and test-retest reliability was stable (ICC = 0.97). Conclusions: The AR-PAID scale is a valid and reliable instrument for diabetes-distress screening in primary care patients with T2DM that can be used in clinical settings and research. Further research is needed to validate short forms of the AR-PAID scale.
